Abstract:
The state-of-the-art on thaumasite formation is discussed, stressing aspects of its formation in mortars an in portland-cement concretes, and also the effect its formation has on their durability. Methods for material synthesis, mentioned in the bibliography including a detailed report of the characterization of thaumasite through XRD, IR, DTA/TG, NMR, electron microscopy and microanalysis, are described.
